Fig. 12 is a side View of the drive gearing of the form of my invention shown in Figs. 8 to 11 inclusive.

Corresponding parts are designated by the same reference characters in all the figures.

My invention comprises primarily a segmental reversing gear wheel 1, a vertical driven shaft 2 on which said gear wheel is operatively mounted, and a driving pinion 3 in mesh with said gear wheel.

The gear wheel 1 comprises a segmental member 4 formed with gear teeth'5 along its lower side face, gear teeth 6 along. its upper face, and gear teeth 7 and 8 extending around the ends respectively of said member from the lower face teeth 5 to the upper face teeth 6, thus providing a continuous row of teeth extending from one end of the gear wheel to the other end along the'lower side thereof andaround said other end of the guide rollers 24 and 25 journaled on arms 26 pivgear wheel and along the upper side to said first end thereof and around said first end of the gear wheel to the teeth at said end on the lower side of the gear wheel. Guide rings 9 and 10 are secured on the gear wheel 1 below and above the same, respectively, in spaced relation from the gear wheel, by bolts 11 and nuts 12, and spacing tubes 13 and 14, the spacing tubes 13 being interposed between the gear wheel and the ring 9 and the spacing tubes 14 being interposed between the gear wheel and the ring 10, for spacing said rings from the lower and upper sides respectively of the gear wheel at the proper distance to receive the pinion 3 between lower side of the gear and the ring 9, and the upper side of the gear and the ring 10.

End guides 15 and 16 are secured between the guide rings 9 and 10, and are spaced from the ends V respectively of the gear wheel at a distance sufficient to allow'the pinion 3 to pass between said end guides and the ends of the gear wheel. The

segmental gear wheel 1 is formed with a shroud 17, around the inner end of the gear teeth, for

engagement with a shroud 18 on the inner end of the pinion 3 for maintaining the teeth of the gear and pinion in loose mesh and preventing too deep or close a mesh of the teeth of said gear and pinion.

The pinion 3 is secured on a drive shaft 19 journaled in a bearing 20 on a frame'2l, and a roller 22 is journaled on said shaft at the outer end of the pinion for engagement with the guide rings 9 and 10 and the end guides 15 and 16, whereby the teeth of the pinion are maintained in mesh with the teeth 5, 6, 7 and 8 respectively of'the gear wheel 1. a

The gear wheel 1 is mounted on the driven shaft 2 by means of a universal joint 23 and the guide rings 9 and 10 are engaged respectively by oted on the frame 21 at 27, whereby the gear wheel 1 is guided and maintained in operative position. 1 l

On the upper end of the driven shaft 2 is secured a power pulley 28 to which is connected 2. pull line 29 which may be connected to the sucker rod of deep well pump for reciprocating said sucker rodfor operating the pump. 7

On the pinion shaft 19 is secured a worm gear 30 in mesh with a worm 31 .on the shaft 32 of a motor 33. v The operation of the form of my invention above described is as follows:

Power being applied to the motor 33, the pinion 3 is rotated by the motor, through the motor shaft 32, worm 31, worm gear 30 and pinion shaft 19, whereupon the pinion 3, meshing with the gear teeth 5, rotates the gear wheel 1, shaft 2 and pulley 28 in one direction, and the pinion meshing with gear teeth 6 rotates said gear wheel, shaft and pulley in the opposite direction, giving the gear 1, shaft 2 and pulley 28 an oscillating motion, or an intermittent rotary motion, first in one direction and then in the other direction, the pinion meshing with the end teeth '7 and passing around one end of the gear wheel 1 from the teeth 6 to the teeth 5, and said pinion meshing with the end teeth 3 and passing around the other end of the gear wheel from the teeth 5 to the teeth 6 to reverse the rotation of the gear wheel, while the universal joint 23 permits the gear wheel 1 to rock or change its axial position to enable said pinion to travel around the ends of the gear wheel from the teeth 6 to the teeth 5 of said gear wheel and vice versa. As the power wheel 28 is oscillated the pull line 29 reciprocates the sucker rod of a deep well pump.

In the form of my invention shown in Figs. 5 and 6 a segmental reversible gear 40 is mounted, by means of a universal joint 41, on a horizontal driven shaft 42. The gear 40 is formed with teeth 43 and 44 respectively along its side faces, and with teeth 45 and 46 at its ends respectively, said teeth 45 extending around one end of the gear from the teeth 43 to the teeth 44 and the teeth 46 extending around the other end of the gear from the teeth 44 to the teeth 43. A shroud 47 is formed on the gear at the inner end of the teeth 43 to 46 inclusive. The gear is formed with side guides 48 and 49 which are spaced respectively from the side teeth 43 and 44 of the gear, and the gear is provided with end guides 50 and 51 spaced respectively from the end teeth 45 and 46 of the gear. A pinion 52, secured on a vertical drive shaft 53, meshes with the teeth of the gear 40, said pinion being formed with a shroud 54 at its inner end for engaging the shroud 4'7 to maintain the teeth of the pinion 52 in free mesh with the teeth of the gear 40 and to prevent too deep a mesh of the teeth of said pinion and gear. A roller 55 is journaled on the pinion shaft 53 for engaging the guides 48, 49, 50 and 51 for maintaining the teeth of the pinion in mesh with the teeth 43, 44, 45 and 46 respectively of the gear.

The vertical drive shaft 53 is journaled in bearings 56 and a worm gear 57 is secured on said vertical shaft in mesh with a worm 58 on the shaft 59 of a motor 60.

The horizontal driven shaft 42 is journaled in bearings 61, 62 and 63 on the upper end of standards 64, .65 and 66 respectively and a power pulley 67 is secured on said driven shaft to which power pulley a pull line 68 is connected, which in turn connects to the sucker rod of a deep well pump or to any other mechanism to be driven.

The operation of this form of my invention is as follows:

The pinion 52, being rotated by the motor throughmotor shaft 59, worm 58, worm gear 57 and vertical shaft 53, and the pinion meshing successively with the gear teeth 43, 45, 44 and 46 causes said gear, driven shaft 42 and power pulley 67 to oscillate, whereby the pull line 68 reciprocates the sucker rod of a deep well pump or operates any suitable machine to which said line is connected.

In the form of my invention shown in Figs. 8 to 10 inclusive a continuous, reversing segmental gear wheel '70 is slidably mounted on a driven shaft '71 by means of a ball bearing '72,

the portion '73 of said shaft, on which the hub '74 of said gear wheel slides, being square, and. the hub having a square opening '75 to receive said square portion of said shaft and said ball hearing. The gear wheel 70 is formed with teeth '76 and '77 on its side faces respectively and with end teeth 78 and 79 on the ends respectively of the gear wheel, said end teeth leading from the teeth '76 to the teeth '77 and from the teeth '77 to the teeth 76 around the ends respectively of the gear wheel. On the gear wheel '7 0 are formed end guides 80 and 81 and a shroud 82 is formed on the gear wheel at the inner end of the gear teeth '76, '77,. '78 and '79 for the purpose hereinafter described. A pinion 83 secured on the upper end of a vertical shaft 84 meshes with the teeth '76, '7'7, '78 and '79 of the gear wheel '70. The pinion shaft 84 is journaled in a gear housing 85 and is driven by a motor 86 through the medium of motor shaft 87, pinion 88 on said motor shaft, gear 89, pinion 90, worm 91 and worm gear 92, the pinion 90 and Worm 91 being formed integral with each other to rotate together, and the worm gear 92 being secured on the pinion shaft 84. The pinion 83 is formed with a shroud 93 at its upper end for engaging the shroud 82 on the gear wheel 70 to prevent too deep a mesh of the teeth of the pinion and the teeth of the gear wheel. A roller 94 is journaled on the pinion shaft 84 for engaging the guides 80 and 81 for maintaining the teeth of the pinion 83 in mesh with the teeth '78 and '79 respectively of the gear wheel '70 as the pinion passes around the ends respectively of the gear wheel from one side thereof to the other. The driven shaft 71 is journaled in bearings 95 and 96 on the frame 9'7 of the mechanism. Vertical slide bearings 98 and 99 are formed on the frame 97 in which slides 100 and 101 are respectively mounted, which slides carry rollers 102 and 103 respectively engaging cams 104 and 105 respectively, which cams are secured on a cam shaft 106 journaled in the frame 9'7. The cam shaft 106 and the cams 104 and 105 are driven from the gear 89 through an idler pinion 107 and a cam pinion 108 secured on said cam shaft. The upper end of the slide 100 is connected to one end of a link 109, the other end of which is connected to one end of a pair of links 110 and 111, which links are connected respectively at their other ends to the bearing 95 of the driven shaft '71 and to the hub '74 of the gear wheel '70. The upper end of the slide 101 is connected to one end of a link 112, the other end of which is connected to one end of a pair of links 113 and 114, which links are connected respectively at their other ends to the bearing 96 of the driven shaft '71 and to the hub '74 of the gear wheel 70. A power pulley 115 is secured on the driven shaft '71 and a pulley line 116 is secured to said power pulley.

The operation of this form of my invention is as follows:

The pinion 83, being rotated by the motor 86, through motor shaft 8'7, pinion 88, gear 89, pinion 90, worm 91, worm gear 92 and vertical shaft 84, said pinion meshes successively with the gear teeth '76, '78, '7'7 and '79, etc., and oscillates the segmental gear 70, shaft '71 and power pulley 115 and the pull line connected to the sucker rod of a deep well pump operates said pump. As the pinion 83 meshes with the end teeth '78, the cams 104 and 105, engaging the cam rollers 102 and 103 respectively, lower the slide 100 and raise the slide 101, whereupon the gear wheel '70 is shifted to the left on the driven shaft '71 by said slide 100, and links 109, 110 and 111 and the pinion 83 passes around the end of the segmental gear wheel and meshes with the gear teeth '77. As the pinion 83 meshes with the teeth 79, the cams 104 and 105, engaging the cam rollers 102 and 103 respectively, raise the slide 100 and lower the slide 101, whereupon the gear wheel 70 is shifted to the right on the driven shaft '71 by the slide 101 and links 112, 113 and 114, and the pinion 83 passes around the end of the segmental gear wheel and meshes with the gearteeth 76.
